Indoor exhibitions

 
The museum’s permanent exhibition sheds light on the fortification of Finland’s eastern border in Virolahti in 1940–1941 and 1944. The museum is part of the wartime line of defence that extends from the Gulf of Finland to Salla and, as field fortifications, all the way to the Arctic Ocean. The line of defence can rightly be called Finland’s largest construction project, having employed not only military personnel but also as many as 35,000 civilian builders and 2,000 female volunteers.
 
The museums brand new permanent exhibition, opened in the summer of 2015, engages the visitor to a multisensory experience through the visit. The exhibition captures the different stages of work and presents builders working in the construction site.
